Taking an essentially standard MR762A1 (caliber 7.62 x 51 mm NATO) semi- automatic rifle, Heckler & Koch USA turns it into a more effective precision rifle by an astute addition of the right accessories. Featured is a HK G28 adjustable cheekpiece buttstock, and LaRue Tactical BRM-S bipod are the primary add-ons that make the MR762A1 Long Rifle Package (LRP) more than a sum of parts. The MR762A1 LRP employs the same HK proprietary gas piston operating system found on current HK rifles and carbines, using a "pusher" rod in place of the gas tube normally found in AR15/M16/M4-style firearms. This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. It uses a barrel produced by Heckler & Koch's famous cold hammer forging process. The highest quality steel is used in this manufacturing process, producing a long-life barrel that provides superior performance with minimal degradation of accuracy and muzzle velocity after prolonged use. The MR762A1 used in the "Long Rifle Package" features additional accessories and add-ons which includes an ERGO Pistol Grip from Falcon Industries, the same Blue Force Gear sling used on the HK M27 IAR supplied to the USMC, and an OTIS cleaning kit. The rifle package, complete with one 20 and one 10-round magazine in a compact 42-inch Model 1720 Pelican case.
